European guideline (EuroGuiDerm) on atopic eczema - part II: non-systemic treatments and treatment recommendations for special AE patient populations. J Eur Acad Dermatol Venereol 2022; 36:1904-1926. [PMID: 36056736 DOI: 10.1111/jdv.18429] [Citation(s) in RCA: 59] [Impact Index Per Article: 29.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2022] [Accepted: 06/03/2022] [Indexed: 12/01/2022]
Abstract
The evidence- and consensus-based guideline on atopic eczema was developed in accordance with the EuroGuiDerm Guideline and Consensus Statement Development Manual. Four consensus conferences were held between December 2020 and July 2021. Twenty-nine experts (including clinicians and patient representatives) from 12 European countries participated. This second part of the guideline includes recommendations and detailed information on basic therapy with emollients and moisturizers, topical anti-inflammatory treatment, antimicrobial and antipruritic treatment and UV phototherapy. Furthermore, this part of the guideline covers techniques for avoiding provocation factors, as well as dietary interventions, immunotherapy, complementary medicine and educational interventions for patients with atopic eczema and deals with occupational and psychodermatological aspects of the disease. It also contains guidance on treatment for paediatric and adolescent patients and pregnant or breastfeeding women, as well as considerations for patients who want to have a child. A chapter on the patient perspective is also provided. The first part of the guideline, published separately, contains recommendations and guidance on systemic treatment with conventional immunosuppressive drugs, biologics and janus kinase (JAK) inhibitors, as well as information on the scope and purpose of the guideline, and a section on guideline methodology.

Abstract
INTRODUCTION AND OBJECTIVES Atopic dermatitis (AD) is the most common cutaneous inflammatory disease in both adults and children. Although emerging therapeutic approaches are being investigated for the management of pediatric AD, it still needs to be managed with conventional treatments. This consensus document is aimed at providing an update on general management and therapies of pediatric AD, defining practical recommendations for using both topical and systemic agents. MATERIAL AND METHODS A panel of experts consisting of dermatologists and pediatricians were convened in order to define statements, through a Delphi process, standardizing the management of AD in pediatric subjects in a real-world setting. RESULTS A set of practical recommendations obtaining an at least 75% agreement was presented. CONCLUSIONS This set of practical recommendations represents a simple and fast snapshot on the pediatric use of common anti-AD therapeutics.

Dismissing the fallacies of childhood eczema management: case scenarios and an overview of best practices. Drugs Context 2018; 7:212547. [PMID: 30532792 PMCID: PMC6281040 DOI: 10.7573/dic.212547] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2018] [Revised: 09/03/2018] [Accepted: 09/04/2018] [Indexed: 12/19/2022] Open
Abstract
BACKGROUND Eczema or atopic dermatitis (AD) is a common relapsing childhood dermatologic illness. Treatment of AD is primarily topical with emollients and corticosteroid/calcineurin inhibitor, which is efficacious for the majority of patients. However, AD is often complicated and difficult to manage in many Asian cities. Effective therapy is impeded by fallacies in the following aspects: (1) mistrust and unrealistic expectations about Western medicine, (2) skin care and allergy treatment, (3) ambiguity about optimal bathing and moisturizing, (4) hesitation and phobias about the usage of adequate topical corticosteroid and immunomodulatory therapies, (5) food and aeroallergen avoidance and dietary supplementation, and (6) complementary and alternative therapies. METHODS AND RESULTS Eleven anonymized case scenarios are described to illustrate issues associated with these fallacies. A literature review is performed and possible solutions to handle or dismiss these fallacies are discussed. CONCLUSIONS The first step in patient care is to accurately assess the patient and the family to evaluate possible concerns, anxiety, and phobias that could impede therapeutic efficacy. Education about the disease should be individualized. Conflicting recommendations on the usage of topical steroid have a detrimental effect on management outcomes, which must be avoided.

Consensus-based European guidelines for treatment of atopic eczema (atopic dermatitis) in adults and children: part I. J Eur Acad Dermatol Venereol 2018; 32:657-682. [PMID: 29676534 DOI: 10.1111/jdv.14891] [Citation(s) in RCA: 496] [Impact Index Per Article: 82.7] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2017] [Accepted: 01/29/2018] [Indexed: 12/12/2022]
Abstract
This guideline was developed as a joint interdisciplinary European project, including physicians from all relevant disciplines as well as patients. It is a consensus-based guideline, taking available evidence from other guidelines, systematic reviews and published studies into account. This first part of the guideline covers methods, patient perspective, general measures and avoidance strategies, basic emollient treatment and bathing, dietary intervention, topical anti-inflammatory therapy, phototherapy and antipruritic therapy, whereas the second part covers antimicrobial therapy, systemic treatment, allergen-specific immunotherapy, complementary medicine, psychosomatic counselling and educational interventions. Management of AE must consider the individual clinical variability of the disease; highly standardized treatment rules are not recommended. Basic therapy is focused on treatment of disturbed barrier function by hydrating and lubricating topical treatment, besides further avoidance of specific and unspecific provocation factors. Topical anti-inflammatory treatment based on glucocorticosteroids and calcineurin inhibitors is used for flare management and for proactive therapy for long-term control. Topical corticosteroids remain the mainstay of therapy, whereas tacrolimus and pimecrolimus are preferred in sensitive skin areas and for long-term use. Topical phosphodiesterase inhibitors may be a treatment alternative when available. Adjuvant therapy includes UV irradiation, preferably with UVB 311 nm or UVA1. Pruritus is targeted with the majority of the recommended therapies, but some patients may need additional antipruritic therapy. Antimicrobial therapy, systemic anti-inflammatory treatment, immunotherapy, complementary medicine and educational intervention will be addressed in part II of the guideline.

Association of atopy and tentative diagnosis of skin cancer - results from occupational skin cancer screenings. J Eur Acad Dermatol Venereol 2017; 31:2083-2087. [PMID: 28681396 DOI: 10.1111/jdv.14456] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2017] [Accepted: 06/28/2017] [Indexed: 12/22/2022]
Abstract
BACKGROUND The relationship between atopic conditions and carcinoma of the skin has been described inconsistently. Population-based data providing information on atopic diseases as well as on skin cancer are sparse. OBJECTIVE To determine the correlation between atopy and prevalence of precanceroses, non-melanoma skin cancer and malignant melanoma (MM), while taking into account known risk factors for skin cancer. METHODS Data from occupational skin cancer screenings were analysed in a cross-sectional study. Dermatologists performed whole body examinations and collected medical histories. Subjects comprised all employees (16-70 years) examined from 2006 to 2014. 'Atopy' was defined by clinical screening diagnosis and/or by participant-reported, pre-existing atopic dermatitis, allergic asthma or other specified allergies confirmed by a physician. Tentative screening diagnoses of skin cancer related to actinic keratosis, basal cell carcinoma and malignant melanoma. RESULTS The study cohort comprised 90 265 employees (mean age 43 ± 11 years, 58.5% male), 30.7% of whom were ever diagnosed with an atopic disease. Persons with atopic conditions recorded in their medical history and at the time of screening had a significantly lower prevalence of actinic keratosis (AK), basal cell carcinoma (BCC) and MM. After controlling for age, sex and relevant risk factors (skin type, childhood sun burns), atopy remained significantly protective against BCC (OR 0.77) and MM (OR 0.53). CONCLUSION Design limitations of the study include that all findings of skin cancer were based on clinical examination only and must therefore be considered tentative diagnoses. Furthermore, owing to the cross-sectional study design, causal pathways cannot be proven. However, analyses of data from such a large and general population-based cohort afford valuable insights into the relationship between atopic diseases and skin cancer. They provide the grounds for prospective cohort studies to evaluate and dissect the underlying mechanism.

Abstract
Hand dermatitis is a socially significant health problem. This review provides a discussion on the clinical features and patterns as well as the differential diagnosis of hand dermatitis, because these are essential for proper diagnosis in clinical practice. The morphology, however, is poorly related to the etiology in chronic cases. In all cases of chronic hand dermatitis, a full diagnostic examination should be undertaken and the etiology should be clarified and addressed in the treatment concept, instead of just moving directly from a morphological diagnosis to therapy. Preventive measures should be included in the treatment concept according to etiology. A stepwise approach for escalating therapy is advised, including basic topical therapy, topical corticosteroids, calcineurin inhibitors, as well as phototherapy and systemic therapy with corticosteroids, alitretinoin, cyclosporine, methotrexate, azathioprine, and others.

Abstract
BACKGROUND Atopic dermatitis (AD) (or atopic eczema) is a chronic inflammatory skin condition that affects children and adults and has an important impact on quality of life. Topical corticosteroids (TCS) are the first-line therapy for this condition; however, they can be associated with significant adverse effects when used chronically. Tacrolimus ointment (in its 2 manufactured strengths of 0.1% and 0.03%) might be an alternative treatment. Tacrolimus, together with pimecrolimus, are drugs called topical calcineurin inhibitors (TCIs). OBJECTIVES To assess the efficacy and safety of topical tacrolimus for moderate and severe atopic dermatitis compared with other active treatments. SEARCH METHODS We searched the following databases up to 3 June 2015: the Cochrane Skin Group Specialised Register, CENTRAL in the Cochrane Library (Issue 5, 2015), MEDLINE (from 1946), EMBASE (from 1974), LILACS (from 1982), and the Global Resource of Eczema Trials (GREAT database). We searched six trials registers and checked the bibliographies of included studies for further references to relevant trials. We contacted specialists in the field for unpublished data.A separate search for adverse effects of topical tacrolimus was undertaken in MEDLINE and EMBASE on 30 July 2013. We also scrutinised the U.S. Food and Drug Administration (FDA) websites for adverse effects information. SELECTION CRITERIA All randomised controlled trials (RCTs) of participants with moderate to severe atopic dermatitis (both children and adults) using topical tacrolimus at any dose, course duration, and follow-up time compared with other active treatments. DATA COLLECTION AND ANALYSIS Two authors independently screened and examined the full text of selected studies for compliance with eligibility criteria, risk of bias, and data extraction. Our three prespecified primary outcomes were physician's assessment, participant's self-assessment of improvement, and adverse effects. Our secondary outcomes included assessment of improvement of the disease by validated or objective measures, such as SCORAD (SCORing Atopic Dermatitis), the EASI (Eczema Area and Severity Index), and BSA (Body Surface Area) scores. MAIN RESULTS We included 20 studies, with 5885 participants. The variability of drug doses, outcomes, and follow-up periods made it difficult to carry out meta-analyses.A single trial showed that tacrolimus 0.1% was better than low-potency TCS by the physician's assessment (risk ratio (RR) 3.09, 95% confidence interval (CI) 2.14 to 4.45, 1 study, n = 371, moderate-quality evidence). It was also marginally better than low-potency TCS on face and neck areas and moderate-potency TCS on the trunk and extremities by the physician's assessment (RR 1.32, 95% CI 1.17 to 1.49, 1 study, n = 972, moderate level of evidence) and for some of the secondary outcomes. Compared with pimecrolimus 1%, people treated with tacrolimus were almost twice as likely to improve by the physician's assessment (RR 1.80, 95% CI 1.34 to 2.42, 2 studies, n = 506, moderate quality of evidence). Compared with the lower concentration of 0.03%, the tacrolimus 0.1% formulation reduced the risk of not having an improvement by 18% as evaluated by the physician's assessment (RR 0.82, 95% CI 0.72 to 0.92, 6 studies, n = 1640, high-quality evidence). Tacrolimus 0.1% compared with moderate-to-potent TCS showed no difference by the physician's assessment, and 2 secondary outcomes (1 study, 377 participants) and a marginal benefit favouring tacrolimus 0.1% was found by the participant's assessment (RR 1.21, 95% CI 1.13 to 1.29, 1 study, n = 974, low quality of evidence) and SCORAD.Based on data from 2 trials, tacrolimus 0.03% was superior to mild TCS for the physician's assessment (RR 2.58, 95% CI 1.96 to 3.38, 2 studies, n = 790, moderate-quality evidence) and the participant's self-assessment (RR 1.64, 95% CI 1.41 to 1.90, 1 study, n = 416, moderate quality of evidence). One trial showed moderate benefit of tacrolimus 0.03% compared with pimecrolimus 1% on the physician's assessment (RR 1.42, 95% CI 1.02 to 1.98, 1 study, n = 139, low-quality evidence), but the effects were equivocal when evaluating BSA. In the comparison of tacrolimus 0.03% with moderate-to-potent corticosteroids, no difference was found in most of the outcomes measured (including physician's and participant's assessment and also for the secondary outcomes), but in two studies, a marginal benefit favouring the corticosteroid group was found for the EASI and BSA scores.Burning was more frequent in those using calcineurin inhibitors than those using corticosteroid tacrolimus 0.03% (RR 2.48, 95% CI 1.96 to 3.14, 5 studies, 1883 participants, high-quality evidence), but no difference was found for skin infections. Symptoms observed were mild and transient. The comparison between the two calcineurin inhibitors (pimecrolimus and tacrolimus) showed the same overall incidence of adverse events, but with a small difference in the frequency of local effects.Serious adverse events were rare; occurred in both the tacrolimus and corticosteroid groups; and in most cases, were considered to be unrelated to the treatment. No cases of lymphoma were noted in the included studies nor in the non-comparative studies. Cases were only noted in spontaneous reports, cohorts, and case-control studies. Systemic absorption was rarely detectable, only in low levels, and this decreased with time. Exception is made for diseases with severe barrier defects, such as Netherton's syndrome, lamellar ichthyosis, and a few others, with case reports of a higher absorption. We evaluated clinical trials; case reports; and in vivo, in vitro, and animal studies; and didn't find any evidence that topical tacrolimus could cause skin atrophy. AUTHORS' CONCLUSIONS Tacrolimus 0.1% was better than low-potency corticosteroids, pimecrolimus 1%, and tacrolimus 0.03%. Results were equivocal when comparing both dose formulations to moderate-to-potent corticosteroids. Tacrolimus 0.03% was superior to mild corticosteroids and pimecrolimus. Both tacrolimus formulations seemed to be safe, and no evidence was found to support the possible increased risk of malignancies or skin atrophy with their use. The reliability and strength of the evidence was limited by the lack of data; thus, findings of this review should be interpreted with caution. We did not evaluate costs.

Abstract
Atopic dermatitis (AD) is a distressing dermatological disease, which is highly prevalent during infancy, can persist into later life and requires long-term management with anti-inflammatory compounds. The introduction of the topical calcineurin inhibitors (TCIs), tacrolimus and pimecrolimus, more than 10 yr ago was a major breakthrough for the topical anti-inflammatory treatment of AD. Pimecrolimus 1% is approved for second-line use in children (≥2 yr old) and adults with mild-to-moderate AD. The age restriction was emphasized in a boxed warning added by the FDA in January 2006, which also highlights the lack of long-term safety data and the theoretical risk of skin malignancy and lymphoma. Since then, pimecrolimus has been extensively investigated in short- and long-term studies including over 4000 infants (<2 yr old). These studies showed that pimecrolimus effectively treats AD in infants, with sustained improvement with long-term intermittent use. Unlike topical corticosteroids, long-term TCI use does not carry the risks of skin atrophy, impaired epidermal barrier function or enhanced percutaneous absorption, and so is suitable for AD treatment especially in sensitive skin areas. Most importantly, the studies of pimecrolimus in infants provided no evidence for systemic immunosuppression, and a comprehensive body of evidence from clinical studies, post-marketing surveillance and epidemiological investigations does not support potential safety concerns. In conclusion, the authors consider that the labelling restrictions regarding the use of pimecrolimus in infants are no longer justified and recommend that the validity of the boxed warning for TCIs should be reconsidered.

Abstract
The existing evidence for treatment of atopic eczema (atopic dermatitis, AE) is evaluated using the national standard Appraisal of Guidelines Research and Evaluation. The consensus process consisted of a nominal group process and a DELPHI procedure. Management of AE must consider the individual symptomatic variability of the disease. Basic therapy is focused on hydrating topical treatment, and avoidance of specific and unspecific provocation factors. Anti-inflammatory treatment based on topical glucocorticosteroids and topical calcineurin inhibitors (TCI) is used for exacerbation management and more recently for proactive therapy in selected cases. Topical corticosteroids remain the mainstay of therapy, but the TCI tacrolimus and pimecrolimus are preferred in certain locations. Systemic immune-suppressive treatment is an option for severe refractory cases. Microbial colonization and superinfection may induce disease exacerbation and can justify additional antimicrobial treatment. Adjuvant therapy includes UV irradiation preferably with UVA1 wavelength or UVB 311 nm. Dietary recommendations should be specific and given only in diagnosed individual food allergy. Allergen-specific immunotherapy to aeroallergens may be useful in selected cases. Stress-induced exacerbations may make psychosomatic counselling recommendable. 'Eczema school' educational programs have been proven to be helpful. Pruritus is targeted with the majority of the recommended therapies, but some patients need additional antipruritic therapies.

Abstract
Background In recent years, pimecrolimus 1% cream has been demonstrated to reduce symptoms of atopic dermatitis in patients when applied topically. Material/Methods In our study we compared the therapeutic effects of local 1% pimecrolimus to 1% hydrocortisone, and to a control group in a mouse model with atopic dermatitis in the external ear canals. Atopic dermatitis was created by application of Dinitrochlorobenzene in the external ear canals of mice. The development of atopic dermatitis was detected by clinical observation score and determination of total serum IgE levels. Pimecrolimus and hydrocortisone cream were topically applied to the external ear canal skin once a day for 14 days. Results There was no significant difference between the hydrocortisone and the pimecrolimus therapy groups, while there was a statistically significant difference between these 2 groups and the control group (p<0.05) Assessment of the clinical observation scoring carried out on the 14th day of therapy revealed that there was no difference between the hydrocortisone and pimecrolimus groups. Biopsies were taken on the 14th day following treatment. Tissue samples were histologically evaluated; contact dermatitis was observed microscopically in the control group, but in the therapy groups only minimal evidence of contact dermatitis was found. Conclusions The results of our study reveal that the therapeutic efficacy of 1% pimecrolimus was equivalent to 1% hydrocortisone treatment in the artificially developed atopic dermatitis model in external ear canals of mice. These results clearly demonstrate that 1% pimecrolimus cream can be an effective alternative therapeutic agent in cases where steroid treatment proves to be insufficient or in cases where treatment must be discontinued due to its adverse effects.

Abstract
Atopic dermatitis is a common chronic skin disorder whose management is complex. Topical corticosteroids have been the mainstay of atopic dermatitis treatment for more than 50 years but have multiple side effects. Topical calcineurin inhibitors including tacrolimus and pimecrolimus are safe and efficacious in atopic dermatitis. In 2005 the FDA issued "black box" warnings for pimecrolimus cream and tacrolimus ointment because of potential safety risks, including skin cancers and lymphomas. However, these concerns are not supported by current data. Topical calcineurin inhibitors are particularly indicated for treating patients with atopic dermatitis in whom topical corticosteroid therapy cannot be employed or may cause irreversible side effects. They can be used advantageously in problem zones. A novel regimen of proactive treatment has been shown to prevent, delay and reduce exacerbations of atopic dermatitis. Therapy with topical calcineurin inhibitors should be managed by an experienced specialist and each patient should receive proper education on how to use them and what possible unwanted effects may be expected.

Abstract
BACKGROUND/PURPOSE Pimecrolimus is a topical immunomodulator for atopic dermatitis. Concerns regarding malignancy risk resulted in its black box warning in 2006. The purpose of this study is to determine the effects of pimecrolimus on Langerhans cells (LC), mediators of the cutaneous immunity UV-irradiated skin. METHODS A RCT was conducted investigating pimecrolimus 1% cream vs triamcinolone 0.1% cream on UV-irradiated epidermal LC on 20 healthy volunteers. Punch biopsies were stained with antibodies to CD1a, HLADR and CD83. RESULTS Triamcinolone caused more depletion in UV-irradiated CD1a(+) epidermis relative to pimecrolimus treatment. (P=0.030). Using HLA-DR as a pan-marker for APCs, pimecrolimus caused marginally less depletion than triamcinolone (P=0.013). Using anti-CD83 as a maturation marker, UV-irradiated skin treated with pimecrolimus showed more mature LC than skin treated with triamcinolone (P=0.00090). CONCLUSION UV-induced changes in LC are minimally affected by pimecrolimus, compared with triamcinolone.

Abstract
Topical therapies constitute the mainstay of dermatological treatments for skin disorders, such as atopic dermatitis, contact dermatitis, psoriasis, or acne. Since some of these diseases are often chronic, treatment duration may last for years and may even last the patient's entire lifetime. Obviously, such long-term therapy may raise safety concerns, which also include the potential photocarcinogenic effect. Most patients are exposed to ultraviolet radiation (UVR) during leisure, work, vacations, or in tanning beds. Additionally, the patients may receive UVR via UVB phototherapy or psoralens plus UVA radiation (PUVA). The use of immunosuppressant's, such as corticosteroids and calcineurin inhibitors, has markedly increased. Patients with skin diseases have benefited from both systemic and topical treatment of both new and established drugs. The issue of a black box warning by the US Food and Drug Administration has increased concerns about photocarcinogenesis, which raises the question: "Are these drugs safe?" This review focuses on the mechanism of action and photocarcinogenic potential of commonly used topical treatments, such as corticosteroids, calcineurin inhibitors, and vitamin D analogs.

Abstract
In this article there were regarded the most frequent side effects that appear in the patients who have been treated with topical tacrolimus, and the association between topical tacrolimus and the development of tumors is unfolded. The irritation in the site of application of the tacrolimus can manifiest as pruritus, sensation of burning and/or eritema located to the area of the application. It is the most frequent side effect, independently of the duration of the study. The cutaneous infections, especially the viral ones, tend to be more numerous in patients with atopic dermatitis that receive topic tacrolimus. After reviewing the medical literature one concludes that nowadays there doesn t exist scientific evidence of an increase of skin cancer, lymphomas or systemic immunosuppression in those patients that use or have used topical tacrolimus. Nevertheless, it is not possible to exclude the possibility that there appear cutaneous and/or systemic long-term side effects.

Abstract
Cutaneous lupus erythematosus (CLE) encompasses a variety of lesions that may be refractory to systemic or topical agents. Discoid lupus erythematosus (DLE) and subacute cutaneous lupus erythematosus (SCLE) are the most common lesions in clinical practice. The topical calcineurin inhibitors, tacrolimus and pimecrolimus, have been used to treat resistant cutaneous lupus since 2002 and inhibit the proliferation and activation of T-cells and suppress immune-mediated cutaneous inflammation. This article reviews the mechanism of action, efficacy, adverse effects, and the recent concern about their possible carcinogenic effect. Although the total number of patients is small and there is only one relevant randomized controlled study, the data are encouraging. Many patients, previously resistant to systemic agents or topical steroids, improved after four weeks of treatment. DLE and SCLE lesions were less responsive, reflecting the chronicity of the lesions, although more than 50% of patients still showed improvement. Topical calcineurin inhibitors may be a safe and effective alternative to topical steroids for CLE although the only approved indication is for atopic dermatitis.

Abstract
Topical pimecrolimus 1% cream (Elidel) [hereafter referred to as topical pimecrolimus] is a nonsteroidal alternative in the treatment of pediatric atopic dermatitis. In vehicle-controlled, short-term, continuous-use trials in pediatric patients with mild to moderate atopic dermatitis, topical pimecrolimus was effective in treating disease symptoms. Topical pimecrolimus was effective in preventing disease flares and reducing the need for topical corticosteroids in longer term, intermittent-use trials. In addition, topical pimecrolimus was associated with improvements in the health-related quality of life (HR-QOL) of pediatric patients with atopic dermatitis and their parents. In vehicle-controlled trials, topical pimecrolimus was generally as well tolerated as vehicle. Topical pimecrolimus showed similar efficacy to topical tacrolimus 0.03% ointment (hereafter topical tacrolimus) in a short-term, continuous-use trial and the two agents had a generally similar tolerability profile. Although comparative data between topical pimecrolimus and topical corticosteroids are lacking in pediatric patients, and the long-term tolerability (beyond 1-2 years) of topical pimecrolimus is yet to be established, topical pimecrolimus is a useful agent in the management of pediatric patients with mild to moderate atopic dermatitis who do not achieve satisfactory treatment with other topical pharmacologic treatments, including topical corticosteroids.

Abstract
Coal tar is an effective treatment for psoriasis and eczema, but it contains several carcinogenic compounds. Occupational and animal studies have shown an increased risk of cancer after exposure to coal tar. Many dermatologists have abandoned this treatment for safety reasons, although the risk of cancer after coal tar in dermatological practice is unclear. This large cohort study included 13,200 patients with psoriasis and eczema. Information on skin disease and treatment, risk factors, and cancer occurrence was retrieved from medical files, questionnaires, and medical registries. Proportional hazards regression was used to evaluate differences in cancer risk by treatment modality. Patients treated with coal tar were compared with a reference category of patients treated with dermatocorticosteroids (assumed to carry no increased cancer risk). The median exposure to coal tar ointments was 6 months (range 1-300 months). Coal tar did not increase the risk of non-skin malignancies (hazard ratio (HR) 0.92; 95% confidence interval (CI) 0.78-1.09), or the risk of skin cancer (HR 1.09; 95% CI 0.69-1.72). This study has sufficient power to show that coal tar treatment is not associated with an increased risk of cancer. These results indicate that coal tar can be maintained as a safe treatment in dermatological practice.

Abstract
BACKGROUND Discoid lupus erythematosus (DLE) is commonly treated with topical agents, the most important of which are glucocorticosteroids. However, prolonged use of these agents, especially on sensitive areas such as the face, may result in side-effects (e.g. atrophy and telangiectases) by altering collagen synthesis. Therefore, alternative treatments are needed for these patients. AIM To investigate and compare the efficacy of topical pimecrolimus 1% cream and topical betamethasone 17-valerate 0.1% cream on facial lesions of DLE. METHODS This was a randomized double-blind pilot study, performed in outpatient clinics of two major referral hospitals. Ten patients aged 20-53 years with moderate to severe DLE of the face were randomized into two groups for 8 weeks of treatment and 8 weeks of follow-up after treatment. In this double-blind study, one group applied pimecrolimus 1% cream twice daily and the other group applied betamethasone valerate 0.1% cream twice daily to facial lesions. Efficacy end-points included a combined score based on evaluation of erythema, infiltration and presence of scale. RESULTS Efficacy end-points showed significant improvement in both groups. A decrease of 86% and 73% in clinical severity scores was obtained for pimecrolimus and betamethasone, respectively (P = 0.043). There was no significant difference between the two groups in terms of efficacy (P = 0.1). No adverse effect was found at the end of the 8-week trial in any of our patients. CONCLUSIONS The efficacy of pimecrolimus 1% cream is comparable with that of betamethasone valerate 0.1% cream in treating facial DLE.

Abstract
BACKGROUND Atopic dermatitis (AD) is a chronic disease characterized by periods of remission and relapse. Therapeutic objectives for AD should be to quickly reduce disease symptoms by targeting pathophysiological pathways, and to provide long-term management by reducing recurrences. OBJECTIVE Calcineurin inhibitors currently appear to be one of the most promising alternative systemic and topical compounds to treat AD. This review focuses on new developments of topical calcineurin inhibitors, therapeutic regimens including long-term management, and prophylaxis of AD. METHODS The published clinical studies that present data on treatment of AD with calcineurin inhibitors were assessed. RESULTS/CONCLUSION Topical calcineurin inhibitors such as tacrolimus and pimecrolimus provide an effective treatment for AD. They are useful for long-term management and prophylaxis of AD. Safety concerns with regard to increased risk for lymphomas or skin cancer could not be confirmed but will remain under careful observation.

Abstract
Atopic, seborrheic, and contact dermatitis can significantly reduce the quality of life of patients and their families. Although differing in specific aspects of their epidemiology, etiology, and pathobiology, all 3 dermatoses are common in the pediatric population, and they share a common treatment approach. Although effective and widely used to manage exacerbations of pediatric dermatitis, the use of topical corticosteroid remains a concern for some physicians and parents because of its potential for systemic absorption and adverse events associated with prolonged use. Newer additions to the dermatitis treatment algorithm, such as the topical calcineurin inhibitors, may provide an effective steroid-sparing treatment option. Adjuvant treatments, such as antihistamines, antifungals, and antibiotics, also can provide benefit in appropriate circumstances. As there is no cure for dermatitis, a comprehensive, multipronged management strategy of preventive measures, such as trigger avoidance and periodic pharmacologic treatment, will provide patients and caregivers with the best opportunity to successfully control the disease.

Abstract
BACKGROUND Atopic dermatitis (AD) is a common, chronic skin disorder characterized by itch and dry skin, which can develop into pruritic red plaques that ooze when scratched. AD flares often occur in anatomic areas where the skin is naturally thin (the face, neck, and intertriginous zones). Such regions, especially the face, are also areas of sensitive skin and need special consideration when being treated. OBJECTIVE This article will briefly review the concepts of thin and sensitive skin and discuss the treatment of AD in such areas. METHODS The MEDLINE database was searched for English-language articles published that contained the text terms atopic dermatitis, sensitive skin, treatment, topical corticosteroids, or topical calcineurin inhibitors. Articles that pertained to the safety and efficacy of various treatments were selected for further review. RESULTS Topical corticosteroids (TCSs) are effective for the treatment of AD in thin and sensitive skin areas, but their use is limited due to adverse events, such as skin thinning, and the potential for impairing the skin barrier. Topical calcineurin inhibitors (TCIs) also provide effective AD treatment without impairing the skin barrier or inducing skin thinning. Although TCIs may be associated with a higher incidence of application-site reactions such as pruritus and skin burning, these symptoms are typically transient and mild to moderate in nature. LIMITATIONS This analysis focused primarily on relatively recent key trials evaluating the treatment of AD in sensitive skin; due to the limited number of controlled trials evaluating TCS agents, consensus statements and comprehensive review articles were used for most of the information pertaining to this therapeutic option. CONCLUSIONS Although both TCSs and TCIs have a place in a long-term, comprehensive treatment strategy for AD, TCIs may have a particular use in thin and sensitive skin areas.

Abstract
Numerous studies have demonstrated the utility of topical tacrolimus ointment in atopic dermatitis. However, there is a concern that local immunosuppression by calcineurin inhibitors may enhance dermal photocarcinogenesis and carcinogenesis. Therefore, we investigated the influence of topical tacrolimus ointment on squamous cell carcinoma formation in hairless female C3.Cg/TifBomTac immunocompetent mice exposed to solar simulated radiation (SSR). In a first experiment, mice (n = 200) had tacrolimus applied on their dorsal skin three times weekly followed by SSR (2, 4 or 6 standard erythema doses, SED) 3-4 h later. Tacrolimus did not reduce the time to tumor development and in the group receiving 4 SED it even had a protective effect (156 days vs 170 days, P = 0.008). In a second experiment, mice (n = 50) were irradiated with 6 SED three times weekly for 3 months and subsequently treated five times weekly with topical tacrolimus to mimic the use of tacrolimus on sun-damaged skin. The median time to the first skin tumor was 234 days in SSR + tacrolimus group compared with 227 days in the only SSR-irradiated group (P = 0.160). In a third experiment, mice (n = 25) had tacrolimus applied on their dorsal skin every day for 1 month, thereafter the group was irradiated with 4 SED three times weekly. The median time to the first skin tumor was 142 days in tacrolimus + SSR group compared with 156 days in the only SSR-irradiated group from experiment 1 (P = 0.363). We conclude that tacrolimus ointment does not accelerate photocarcinogenesis or induce any dermal carcinogenicity in hairless mice.

Abstract
BACKGROUND There is a lack of data with regard to the interaction between ultraviolet (UV) radiation and topical calcineurin inhibitors. OBJECTIVE We aimed to investigate (1) the UV transmission through tacrolimus ointment and (2) the impact of topical exposure to tacrolimus on the protein expression of thymine dimers (TD) and p53 in human skin. METHODS Spectrophotometric measurements (290-400 nm) of tacrolimus ointment and the vehicle were performed. Eight subjects were treated with tacrolimus ointment and the vehicle thrice daily over a 3-day period on the back. Pre-treated sites and one control site were exposed to two minimal erythema doses UVB. Skin biopsies were taken 1h and 24h after irradiation. Immunohistochemical procedures were used for the detection of TD and p53. RESULTS Mean UV transmission was over 94% and did not significantly differ between tacrolimus ointment and the vehicle. Immunohistological examinations of TD and p53 expression did not demonstrate significant differences between irradiated sites, irradiated plus vehicle treated sites, and irradiated plus tacrolimus treated sites both 1h and 24h post-irradiation. CONCLUSIONS The present data suggest that tacrolimus ointment hardly has UV blocking capacities and does not significantly interfere with development and/or removal of local DNA damage in human skin.

Abstract
Atopic dermatitis (AD) is a common disease in children. Despite good skin care and trigger avoidance, many children with AD require pharmacologic treatment to manage their disease. In recent years, topical calcineurin inhibitors (TCIs) have been used as an alternative to topical corticosteroids to treat some children with AD. However, revisions to the US labeling for TCIs (i.e. a boxed warning and a medication guide) have generated concern among pediatricians regarding TCI safety and raised questions about the appropriate use of TCIs in the pediatric population. Data from several well designed studies support the efficacy of TCIs in the treatment of AD. Safety concerns arise from a small number of reported malignancies, animal toxicology studies, and the potential adverse effects (including immunosuppression and risk of lymphoma) observed in patients who received systemically administered calcineurin inhibitors for suppression of solid-organ transplant rejection. Several factors indicate that these effects do not occur with topical administration: (i) systemic levels following topical administration are at least 10-fold lower than with oral administration; (ii) the small number of lymphomas reported to date in persons exposed to TCI use are not consistent with the types seen in transplant patients or other immunosuppressed patients; and (iii) no adverse effects on the immune system (as assessed by measures including vaccination response and skin delayed-type hypersensitivity reaction) have been observed in clinical trials of TCIs in children with AD. Overall, TCIs have an established safety and efficacy profile as long-term maintenance therapy in children with AD.

Abstract
Atopic dermatitis (AD) is a chronic inflammatory disease hypothesized to be the product of complex interactions among the host's environment, susceptibility genes, skin barrier dysfunction, and immune system dysregulation. The objective of this article is to describe the pathobiology and treatment of AD, with particular focus on the role of immune system dysregulation and therapies designed to target this. Literature review indicates that there are immunologic differences between the lesional and non-lesional skin of atopic individuals, and that the non-lesional skin of atopic individuals presents an immunologic profile distinct from that of the skin of healthy individuals. Thus, immune system dysregulation is postulated to be a key contributing factor to the complex etiology of AD. Immunomodulatory agents such as topical corticosteroids (TCSs) and topical calcineurin inhibitors (TCIs), which address the underlying immunopathology of AD, are the foundation for the pharmacologic treatment of flares. TCSs and TCIs both target the inflammatory response responsible for an AD flare but via two distinct mechanisms of action. Whereas TCSs have a more widespread impact on the immune system, the action of TCIs is targeted to the calcineurin pathway and inhibition of T-cell activation. Together, TCSs and TCIs represent the backbone of a long-term treatment strategy for AD.

Abstract
OBJECTIVE Atopic dermatitis (AD) is a common, chronic, inflammatory skin disease that can significantly reduce the quality of life of not only patients but also entire families. This review will focus on the currently available non-pharmacologic and pharmacologic treatments for the control and management of AD. RESEARCH DESIGN AND METHODS A review of English-language articles from January 1953 to May 2006 was performed within the MEDLINE database. Search terms included, but were not limited to, atopic dermatitis, topical corticosteroids, and topical calcineurin inhibitors. Studies evaluating the diagnosis, physical and psychological burden, and underlying pathophysiology of AD were included. Particular focus was placed on literature presenting key safety and efficacy data from clinical trials involving AD treatment. RESULTS Although good skin care and trigger avoidance are fundamental to AD management, most patients also require pharmacologic intervention. Topical therapies comprise the foundation of AD treatment. In particular, topical corticosteroids have been a mainstay in AD treatment for several decades and the newer topical calcineurin inhibitors have become a valuable addition to the therapeutic armamentarium. TCIs are a safe and effective AD treatment; they limit the number of disease flares, extend the time between flares, and provide a steroid-sparing option that may be of particular benefit in the pediatric population. The use of more potent therapies, such as systemic (oral/injected) agents or phototherapy, is typically limited to the treatment of severe, refractory disease. Additionally, owing to the increased risk for bacterial, viral, and fungal infections in patients with AD, topical or systemic antimicrobials are an important component of treatment. LIMITATIONS Case reports and small-scale studies were typically not included in this analysis and owing to the limited number of trials evaluating TCSs, consensus statements and comprehensive review articles were used to obtain information pertaining to the use of this treatment in AD. CONCLUSIONS AD is a common, chronic disease requiring a long-term management strategy that incorporates preventive measures and a multipronged treatment approach.

Abstract
Lupus erythematosus (LE) shows a broad range of cutaneous symptoms, including acute, subacute and chronic lesions. The gold standard of established topical treatment consists of medium- to high-potency corticosteroids. Because face and neck are often involved, adverse effects of prolonged corticosteroid use are not uncommon. There is a need of steroid-free topical treatment in LE. With the development of topical calcineurin inhibitors, tacrolimus and pimecrolimus, there is an alternative available. The present study reviews the literature data on topical tacrolimus and pimecrolimus for malar rash, subacute lesions and discoid chronic lesions among others. The present data argue for an efficacy of these compounds in acute and subacute cutaneous LE manifestations with a rapid response and only minor side-effects when used as an adjunct to systemic treatment. In chronic discoid LE, hypertrophic plaques do not well respond because of limited penetration. The primary target seems to be the decrease or blocking of cytokine production by activated T lymphocytes.

Abstract
Tacrolimus ointment is a topical calcineurin inhibitor (TCI) that was developed specifically for the treatment of atopic dermatitis (AD). It is one of the most extensively tested dermatological products, with more than 19 000 patients (including approximately 7600 children) having participated in the tacrolimus ointment clinical development programme. Recent regulatory reviews have focused on the potential risk of malignancy with TCIs, based on their mode of action and the effects of systemic tacrolimus when given to transplant recipients. Studies have shown, however, that the systemic absorption of tacrolimus when applied topically is very low, with blood concentrations being below the level of quantification in most patients. Moreover, TCIs are not associated with a decrease in immunocompetence in the skin and there is no increase in the incidence of infections with long-term treatment. More than 5.4 million prescriptions for tacrolimus ointment have been issued worldwide, with no evidence of an increased risk of malignancy in adults or children compared with the general population. Similarly, epidemiological studies have failed to demonstrate an increased incidence of skin cancer in patients using TCIs. The most common adverse events (AEs) that occur with tacrolimus ointment treatment are transient application-site reactions, such as burning or pruritus. These complications are related to disease severity, and decrease in frequency over time as AD improves. The incidence of nonapplication-site AEs does not increase with long-term treatment, and most such events occurring in clinical trials were considered to be unrelated to therapy. Although it is important that clinicians are aware of the recent changes in product labelling, extensive clinical trials continue to show that tacrolimus ointment is well tolerated, and is generally an effective therapy for suitable patients with AD.

Abstract
Tacrolimus is an ascomycin macrolactam derivative with immunomodulatory and anti-inflammatory activity that belongs to the class of calcineurin inhibitors. Tacrolimus in its topical formulation has been established as a safe and effective alternative to topical corticosteroids because of its mild side effects and its minimal systemic absorption. Topical tacrolimus has been approved for the treatment of atopic dermatitis in two concentrations, 0.03 and 0.1%. In a thorough research of literature the authors review all of the available data regarding the off-label uses of the medication in other dermatoses. It seems that compared to pimecrolimus, tacrolimus has proved to be a more effective treatment. There is no causal relationship that has been established between tacrolimus and carcinogenesis. Furthermore, the authors believe that, without any evidence, the theoretical concerns are not enough to produce warnings. Tacrolimus ointment 0.1% may be recommended as a first-line choice for seborrheic dermatitis of the face and trunk, facial and intertriginous psoriasis and probably for allergic contact dermatitis and Zoon's balanitis. It has been ineffective in numerous dermatoses such as alopecia areata, necrobiosis lipoidica, internal pruritus and in thick hyperkeratotic plaques of psoriasis when administered as the commercially available formulation without occlusion. There is yet unexploited therapeutic potential regarding the use of topical tacrolimus in dermatology. Isolated cases of successful administration of the medication in various cutaneous conditions require further large-scale studies to clarify the actual effectiveness.

Abstract
The topical calcineurin inhibitors (TCIs) pimecrolimus and tacrolimus are approved for atopic dermatitis but have additional potential in other inflammatory skin diseases. This article reviews their clinical use in non-atopic dermatitis diseases. In seborrheic dermatitis, asteatotic eczema, and contact dermatitis, TCIs are of great benefit and can compete with topical corticosteroids. In psoriasis, TCIs have shown clinical efficacy and safety in facial and intertriginous lesions. Further investigations into possible combinations of TCIs with other established treatments such as UVB irradiation in this disorder are necessary. Initial studies in cutaneous lupus erythematosus have been promising, whereas the response in rosacea and rosacea-like eruptions has been mixed. TCIs have been associated with good clinical responses in oral lichen planus and anogenital lichen sclerosus et atrophicus. In vitiligo, TCIs are associated with some degree of repigmentation, with better results being seen in children and in facial and neck areas. TCIs have a synergistic effect with UVB irradiation in vitiligo. There is a long list of small series and case reports documenting use of TCIs in various other skin conditions that warrant further validation. Although the established mode of action of TCIs is T-cell control, other effects also need to be considered. Specifically, TCIs reduce pruritus and erythema, which cannot be explained by T-cell interactions, and further investigations are needed in these fields.
